provements in- Metallic Sleepers;

This invention relates to improvements in metallic sleepers, andparticularl to that class of sleepers which may be use` asmetal-v licmeansfor flooring when placed upon composition or other reprooffloor-supports.

The invention comprises certain novel constructions, comblnations, .andarraglements o f parts, Vas will be hereinafterl y a portion of a floorand ceiling of a building, showing the similar deta' view s owin suporting-beams, the concrete or similar illlin' g Wit the flooringresting'upon'th'e sur-f. face thereof, and m improved iloorin -securingmeans embedded in the cement` gFig. one form of the iloorin -securinmeans.

The ipipe and lower edgesvof the sleeper are turne to 'one side to form flanges, as at 3 and 4.As shownin these the two portions of the'webs and the anges vmay-be-united at one of the flange edges, as at 5. y When form-' ing thesleeper inthis shape, the said sleeper can be made of a single bent toform'th'e lower rises the corrugated double central portion or web 2,the upper edgesjthereof being turned to one side in .opposite directionsto orm the lysecured and held wi other by bolts or rivets 6, passedthrough the up r flanges 3.

fce of material and l nge 4, from whichA same at suitable intervals."The said rivets Yare referably so secured in place that some resiliencyor yiel quality is left in the web portion of the s eeper. The s acebetween the portions of the web 2 is a apted to receive the greaterportion of securing nails' or pins 7, which are driven through the oor-8 and between the double walls of the lb 2, as clearly'illustrated inFig. 2j of the ra In using my improved securing means or sleeper forfastening `flooring in place in a reproof structure the flooring yisarra cdas usual, being supported upon the lower anges 9 of floor beamsorgirders 10. In the event of tiles being employed in constructing ltheooring the said tiles, as 11, (shQWn-inFig. 1,) are usually archedbetween the,lowe1` pOrtionsof the beams 10 AI mixture of concrete orother suitable material is then placed upon the arched tiling, as shownat 12, the' said mixture being built u above the topv edges of the beams1 0. T then set in position a suitable distance apart and the o fconcrete, cinders, or other material is packed around them until thefireroof material is built up to the surface ofthe i'oftheconcretematerial. Theloo is then 'laid upon the concrete or cementand the s eepers, and the securing-nails 7 are wa betwee'ntheo p's'Vwallsof theslee'perwe s 2. The n or'o er securing means e sleepers 1 areflanges 3 will be flush with the upper surface' driven through theflooring so as to force their ii must force their way between the wallsof the webs and are thus tightly gripped by the as shown in Fig. 2, andes ecially when the material is comparatively t 'n and possessed of someyielding or vspringing qualities.

The entrance of the nails between the por-l tions of the web 2 isfacilitated by the formation .of the saidv webs at their upper. edge.The webs are shaped to form inclined flaring faces, as at 13 and 14. Acomparatively wide entrance to the space between the portions of the webis afforded and the points of the nailsare readily guided to theirposition within the body ortion of the sleeper.

Instead of ma g the sleepers of a single piece of material, as shown inF igs. 1 and 2, it will be evident that the sleepers may be formed oftwo portions 15 and 16, as shown in Figs. 3 and 4. In this event,however, the parts are secured together by bolts or rivets g but asufficient space is left between the web portions to 'receive and holdthe nails.. As

shown in Fig. 3, the fianges of the sleeper may be strengthened byturning their outer edges outward y and then folding them back againupon themselves, as indicated at 17 and 18. Inthis manner comparativelystiff and strong I' fianges are formed u on the sleepers and a good holdis afforded the concrete or other mixture u on the said sleepers andtheir fianges. do not wish, however, to limit myself to the use of thedouble flanges,.for, as

.shown in Fig. 4, the sleepers may be formed of two sections 19 and 2O,vthe upper and lower edges of which are merely turned outwardly to formflanges 21 and 22. 'f

Since the slee ers are only used as an anchoring means or the flooringand not as a supporting means for the material of the fio or or ceiling,it is not necessary that the fianges' be made of great strength, forthere is no coin- -pression or suspension strain u on the same.

The `said sleepers are embedde in the material of the Hoor-support notfor the purpose .of sustaining its weight, but for the purpose ofbinding the wooden flooring to the surface ofv the cement orother-fireproof mixture. Of course it will be understood that Icontemplate using any shaped web and fianges which will form a sleeperof the general type above describe described, ,all within the spirit ofthe invention. I refer, however, the form of sleeper having the doublecorrugated walls and the laterally-extending flanges cap able of beingembedded in a cement, concrete, 0r other mixture, since a resilientspring-retaining means is thus afforded for gripping and holding thenails of the floorin in position.v When forming the sleepers o separatepieces, as shown in Fig. 3, the inwardlyolded edges of the sections maybe made to abut against each other, especially at the lower flange 18,for strengthenin the structure, and the upper folded 'portions of theflanges can be so bent as to provide converging inlet-openings, as at23, for receiving the ends of the'nails.

An important advantage in employing securing-sleepers or anchoring meansof this charaffer accrues from the fact that the said sleepers may bearranged to extend in any direction'with relation to thefloor-supporting beams-that is to say, they can extend parallel withsaid beams or at right angles thereto or oblique thereto, as found mostdesirable for the placing of the flooring.

The great utility of this invention of course lies in the fact thatmetal may be employed for forming the sleepers instead of' wood, woodbeing subject to deterioration, and especially to dry rot when incasedin cement, concrete, or like mixtures. This difficulty is notexperienced in the employment of metallic anchorage for the flooring,and the securing means for holding the flooring in position is thuspractically indestructible.

While the sleepers or anchoring devices 1 vmay be made in considerablelengths, so as to extend, for instance, entirely across a room, it willbe evident that the saidsleepers or anchoring devices may be' made inshort sec- 9 tions placed at intervals, as illustrated in Fig. 5. Insaid figure a series of comparatively short anchoring-sections 24 areillustrated,

which are shown as placed in alinement at v.

given intervals. The construction of the sections is the same as whenthe anchoring devices are made in the form of long or continuoussleepers. p

It will be understood, of course, that the sectional sleepers may bearranged in offset relations to each other, if preferred, instead ofcontinuously in the same line.

` Of course it is desirable that the sleepers or :anchoring devicesshall be arranged transversely or at an angle to the direction of theflooring in order to more securely fasten them `in position, all withinthe spirit of the invention.
